The cathode ray experiment indicated the existence of negatively charged particles in an atom. this experiment also disproved the part of dalton's atomic model that claimed the indivisibility of the atom. when the experiment was repeated using cathodes made of a different metal, each time the results were consistent. these discoveries of thompson were later substantiated by robert millikan when he calculated the charge on an electron.
use information from the passage to justify whether the characteristics of reliable scientific explanations are present in the development of the atomic theory.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
